Walk-In Evaporator Units and How They Work

What are refrigeration evaporator coils? A refrigeration evaporator coil is one of the most important parts of a walk-in cooler or freezer. It absorbs heat when warmer air is passed through a walk-in refrigeration system, thereby cooling the inside of the unit.

In other words, moisture from the air freezes onto the refrigerator evaporator coil—the cooling coils inside the freezer—and helps form a barrier that insulates against heat transfer. Airflow is also minimized as the passages inside the refrigeration evaporator tend to narrow because of build-up of ice. Each walk-in freezer evaporator also features a defrost cycle that helps melt the frost or ice that gradually builds up in the refrigerator evaporator coil. Water that results from the melted ice is then drained from the freezer.

Refrigerator Evaporator Coils Available Here at Rapids

Our refrigerant evaporator units feature an improved design with an easy front access to both electrical and refrigeration components. Smaller cabinet size of these evaporators for refrigeration units make use of optimized space for interiors and provides easier installation and servicing.

Walk-in evaporator units also feature a textured aluminum housing that includes black plastic guards. Take note that low-velocity refrigeration evaporator coils are recommended for floral and sensitive food storage.

In addition, walk-in freezer evaporator units as well as refrigeration evaporator units all come with DOE-compliant EC fan motors. Freezer evaporator units have coil face mount heaters for better defrost, and extended drain pan heaters provide more heat in end compartments. Lastly, improved heater design of the evaporator motor allows for more contact with the coil and drain pan. Automatic defrost timer is also available.
